Hotmail Login Application Visual Basic (Help Needed)

I started building a tabbed webbrowser and i want to make a hotmail login form, to make it able to quickly login to hotmail. This by making two textboxes(one for my e-mail and one for my password) and a button. When i click this button and i filled in my username and password, a new tab is opened and my hotmail is shown. I know how to make a login system but i don't know how to make a login form that directs you to a website. I want to know if it is possible and how I could achieve this to work. Thanx
